Antibodies against Yersinia enterocolitica serotype O:3 lipopolysaccharide present in sera from patients with Yersinia infection were studied by using an enzyme-linked immunosorbent assay. Of the sera with significant bacterial agglutination titers against Y. enterocolitica type O:3, 86% contained anti-lipopolysaccharide antibodies of the immunoglobulin G class. With the sera of some patients, we demonstrated increasing anti-lipopolysaccharide antibody levels of immunoglobulin G class in spite of decreasing bacterial agglutination titers. The assay was specific for lipopolysaccharide from Y. enterocolitica type O:3, and in inhibition experiments lipopolysaccharide could be detected in amounts of greater than or equal to 0.5 micrograms/ml.
采用酶联免疫吸附测定法,对耶尔森氏菌感染患者血清中抗小肠结肠炎耶尔森氏菌O:3血清型脂多糖的抗体进行了研究。在对小肠结肠炎耶尔森氏菌O:3具有显著细菌凝集效价的血清中,86%含有免疫球蛋白G类抗脂多糖抗体。对于一些患者的血清,我们发现尽管细菌凝集效价降低,但免疫球蛋白G类抗脂多糖抗体水平仍在升高。该测定法对小肠结肠炎耶尔森氏菌O:3型脂多糖具有特异性,在抑制实验中,可检测到含量大于或等于0.5微克/毫升的脂多糖。
